Also, in the interests of stopping the constant complaining about the yuri tag I've changed it to 'subtext'. I hope you enjoy reading the manga whether or not it goes romantic enough for your tastes!
I just find it really odd how heavily this series is marketed as a yuri manga in Japan for how little yuri content it actually has.
And that's pretty much the only case I'd ever even consider "not yuri enough" as a criticism, myself: when it is pushed by the publisher as being yuri-heavy.
My actual impression of the manga itself is mostly unrelated to that, though I can't really say it is 100% uncolored by the fact that I thought I was buying something different than what I got.
